All sizes of organizations can benefit from consolidating the workloads of legacy servers onto more powerful systems and climbing the density ladder as their requirements and resources allow. No matter where your business is on the density spectrum, Dell has a number of options through the rack and blade space, as well as highly dense compute nodes that can help move your infrastructure up the density ladder. For a more complete look at the benefits of increasing server density and the offerings that Dell provides to help meet your specific goals, see the full report, “Dell and the Value of Density,” at www.principledtechnologies.com/Dell/Value_of_density_0113.pdf.

HOW INCREASING SERVER DENSITY CAN BENEFIT YOUR BUSINESS
Thriving businesses do more with less, and their datacenters reflect that. How can your business increase usage
density without expanding physical datacenter space? Moving to a denser computing infrastructure—providing the
processing power you need in the smallest possible space—can help you achieve this goal. Using two approaches, both
physical compaction of the datacenter and a logical compression via virtualization, you can maximize the usage of the
space your business already has while improving your bottom line.
Whether you are moving from a small, tower-based server environment to a single blade chassis or from a
legacy rack-server farm to a high-density compute cluster, you can potentially reduce costs related to time,
maintenance, and power by maximizing the density of your applications and datacenter.
WHAT BENEFITS DOES INCREASING DENSITY PROVIDE?
Increasing density has the potential to:
 Reduce management overhead with fewer physical
servers to manage
 Lower the amount of power and cooling, saving on
operating costs
 Save physical space and the costs related to renting
space or building new locations to house servers
 Enable portability of dense computing solutions for
remote locations
 Reduce infrastructure costs with fewer servers to
house and cable
 Reduce datacenter software licensing costs

Common myths about high density
As technology evolves, certain barriers to technology adoption become less relevant. Common myths about high
density computing include:
Myth # 1 - Greater logical
density increases risk of
downtime
Virtualization advances
and high-density hardware
redundancy can actually
provide greater uptime.
Myth #2 - Greater logical
density makes
environments more
difficult to manage
Many systems
management functions are
now directly integrated
into the virtualization
platform.
Myth #3 - Greater physical
density significantly
impedes compute
efficiency
The newest servers
increase density while also
achieving the highest-ever
scores in performance per
watt.
Myth #4 - Greater physical
density is expensive
High-density datacenters
are more power-efficient
than low-density
datacenters, providing
significant cost savings.
WHAT DELL HAS TO OFFER
Dell current-generation PowerEdge R series and PowerEdge M series servers incorporate systems management
features such as the Dell Lifecycle Controller, implement industry-leading power efficiency standards, and are designed
to optimize performance while maintaining low power consumption. Use the overview of Dell PowerEdge servers below

We provide industry-leading technology assessment and fact-based
marketing services. We bring to every assignment extensive experience
with and expertise in all aspects of technology testing and analysis, from
researching new technologies, to developing new methodologies, to
testing with existing and new tools.
When the assessment is complete, we know how to present the results to
a broad range of target audiences. We provide our clients with the
materials they need, from market-focused data to use in their own
collateral to custom sales aids, such as test reports, performance
assessments, and white papers. Every document reflects the results of
our trusted independent analysis.
We provide customized services that focus on our clients’ individual
requirements. Whether the technology involves hardware, software, Web
sites, or services, we offer the experience, expertise, and tools to help our

market readiness, and its quality and reliability.
Our founders, Mark L. Van Name and Bill Catchings, have worked
together in technology assessment for over 20 years. As journalists, they
published over a thousand articles on a wide array of technology subjects.
They created and led the Ziff-Davis Benchmark Operation, which
developed such industry-standard benchmarks as Ziff Davis Media’s
Winstone and WebBench. They founded and led eTesting Labs, and after
the acquisition of that company by Lionbridge Technologies were the
head and CTO of VeriTest.
